As many consumers move along with the trend toward products made without additives, preservatives, or genetically modified organisms, the maker of Similac Advance says it’ll be selling a GMO-free version of the product by the end of the month.

It can be hard to turn your nose up at anything that’s offered for free. But are hospitals doing more harm than good when they give out free samples of brand-name baby formula to mothers of newborn babies?

Jeff says since his local grocery stores put Similac on sale, his daughter hasn’t been able to get the full price back for the recalled Similac she returned because she doesn’t have her receipts. Without proof that she bought it before it went on sale, they will only refund her the sale price. “Who saves grocery receipts?” he writes. “My daughter was out $40 with everything she returned and repurchased a different product.”
